The World Wide Web is based on unique numbers identified as IP addresses and each unit or site that is a part of the Web features such an address. It really is very difficult to remember to go to 22.214.171.124 to load a website though, because of this a much simpler structure was made in the 80s - domain names. Every single domain name features a primary part as well as an extension, for example domain.com or domain.co.uk. Many different extensions exist worldwide - some of them are assigned to countries, such as .co.uk in the abovementioned example, which is given to the United Kingdom, while others are generic, for example .com or .net. Some extensions are available for registration by any entity and others have specific requirements - company registration, regional presence, etcetera. You are able to get a brand new domain from a registrar organization such as ours and if the extension allows domain name transfers, you are able to transfer an existing domain name between registrars too.
